ABSTRACT
Majority of the rural population in India is living in the pre-independence conditions and the economic and technological
advances have widened the rural-urban divide. Developments in Information and Communication technology have given rise
to Geoinformatics which comprise of frontier technologies like Remote Sensing, Geographic information systems (GIS),
photogrammetry and Global positioning system (GPS). Geoinformatics has the potential to enrich rural lives and bring
revolutionary changes. The objective is to bring information collected from diverse sources onto a common platform and
subsequently generate meaningful information by integrating non-spatial data with the thematic maps, using geography as
the common feature so that it can be used for making effective decisions for various planning problems. In this study spatial
data regarding the Land use of Moga district has been extracted from IRS LISS III Satellite data using supervised classifier
Support vector machine (SVM), other linear spatial data has been visually interpreted. Non-spatial tabular data collected
from various government departments has been linked with the village boundary information. The collective spatial and non-
spatial information can be very useful for natural resource management, disaster management, infrastructure development,
health management and various government projects as information when presented in a map format allow a better
perception, visualization of spatial patterns and their relationship with the neighboring areas.
